Meghan Markle and Prince Harry are close to “the point of no return,” according to PR expert Edward Coram-James.

The Duke and Duchess of Sussex were ranked among the least favorite royals of the U.K. public in a recent poll.

Now, Edward says the duo are fast losing appeal to the public of the U.K. and don’t have much time left if they want to get back in the good books of the British people.

“Meghan claims that she’s ‘happier than ever,’ even as her standing in the UK is plummeting, something the latest polls make painfully clear,” Edward told the Express.

“With Prince Harry barely scraping into the top 1,500 most popular public figures and Meghan even lower at 2,034th, their star power in Britain is undeniably fading,” he continued.

Referring to Meghan’s recent comment that she and Harry are in a honeymoon phase and happier than ever, he said, “From her perspective, it’s a clever way to take control of her narrative. It’s quite common for public figures in similar predicaments to shine a light on a confident image when they’re being watched”

He suggested that the Sussexes should make efforts to rehabilitate their image in the U.K.

He said: “They’re not past the point of no return yet, but they’re teetering close. It would take a dramatic shift if they ever hope to reconnect with the UK public.”

“But that door is closing fast as long as they remain embedded in the American celebrity bubble, flashing their brand and embracing the glitz.”

“Many in Britain already feel like outsiders playing royalty in exile. If they don’t shift course soon, they risk being remembered not as changemakers but as a cautionary tale in lost legacy,” he concluded.
